Glider capable of rotating 90 degrees apon impact

[CellularPseudonym]

Hi guys, new user here. I've been playing around with cellular automata for about a year now, mostly through my home-brew Java application.

I've recently added a more powerful way to define rules & neighbourhoods through the use of configurable grids, as seen at the start of the video.

One of the first interesting discoveries I made was a situation where a naturally occurring glider collided with a naturally occurring still-life, resulting in the rotation and continuation of the glider. Neat!

The neighbourhood is a Size-2 Moore neighbourhood, and the two-state (0, 1) totalistic rule (Ranges inclusive of shown numbers) is:

Code: Select all

Become 0 between 10 and [maximum neighbours]
Become 1 between 7 and 8
Become 0 between 0 and 4

Also, it's worth mentioning http://www.reddit.com/r/cellular_automata - a reddit community I frequent, based around the sharing and discussion of CA related content.

Hello world!

Does a zip file containing the Java source code of your program exist anywhere? I found this link:

https://github.com/InfiniteSearchSpace/ ... cience/src

but no archive containing everything.

Sorry about that. The shown program is a fork of my previous project, but I still haven't learnt the ropes with git yet.

Here's a link to a new repo, along with a runnable .JAR for the program used to generate the shown CA: https://github.com/InfiniteSearchSpace/ ... stic-Gen-4

The main controls are mouse-based, utilising Left-click (place blocks), Right-click (play/pause), and Mousewheel-click (clear screen). Mousewheel scrolling defaults to block size, although the bindings can be changed from the "Mousewheel Bind" menu

To configure rulesets & neighbourhoods, create a new 'editor' from the menu. The controls are Left-click (increment cell by 1), Right-click (decrement cell by 1), and Mousewheel-click (set to custom value)

In the editor, to see and/or modify the pre-set neighbourhood and rulesets, use the menu "Rule Config" > "Get Neighbourhood" or "Get Rule", which will populate the grid.

I'll add a video showing the full editing process in a moment.

Perhaps the simplest reaction of this type in CGoL is the boat + G -> G reaction below. The boat is naturally occurring, and the glider occurs in almost any soup.

Code: Select all

x = 9, y = 7, rule = B3/S23
b2o$obo$bo2$6b2o$6bobo$6bo!

On an unrelated note, what happens in your rule when a cell has 5, 6, or 9 neighbors?

Ah, I'll have to check that out. I haven't spent too much time playing with the intricacies of CGoL.

To the individual cell being assessed, no action would be taken. It would retain its current state through to the next generation.
